; Common NRF52 debugging settings follow.  See the Meshtastic developer docs for how to connect SWD debugging probes to your board.

; We want the initial breakpoint at setup() instead of main().  Also we want to enable semihosting at that point so instead of
debug_init_break = tbreak setup
; we just turn off the platformio tbreak and do it in .gdbinit (where we have more flexibility for scripting)
; also we use a permanent breakpoint so it gets reused each time we restart the debugging session?
; debug_init_break = tbreak main

; Note: add "monitor arm semihosting_redirect tcp 4444 all" if you want the stdout from the device to go to that port number instead
; (for use by meshtastic command line)
;  monitor arm semihosting disable
;  monitor debug_level 3
;
; IMPORTANT: fileio must be disabled before using port 5555 - openocd ver 0.12 has a bug where if enabled it never properly parses the special :tt name
; for stdio access.
;   monitor arm semihosting_redirect tcp 5555 stdio

; Also note: it is _impossible_ to do non blocking reads on the semihost console port (an oversight when ARM specified the semihost API).
; So we'll neve be able to general purpose bi-directional communication with the device over semihosting.

; Allows programming and debug via the RAK NanoDAP as the default debugger tool for the RAK4631 (it is only $10!)
; programming time is about the same as the bootloader version.
; For information on this see the meshtastic developers documentation for "Development on the NRF52"
; We manually pass in the elf file so that pyocd can reverse engineer FreeRTOS data (running threads, etc...)
